Fresh guidance increases, a fuel-cell collaboration and a drug-approval filing timetable give Tuesday’s watchlist several distinct catalysts. Backblaze, Harmonic and Aehr Test Systems enter the session following strong overnight reactions, while AMD, Arista Networks and Booking Holdings have confirmed reports due after the close on midterm Election Day.
| Stock | Early premarket move |
|---|---|
| Backblaze (BLZE) | +37.43% |
| Harmonic (HLIT) | +16.19% |
| Aehr Test Systems (AEHR) | +15.60% |
| Lattice Semiconductor (LSCC) | +10.54% |
| Compass Pathways (CMPS) | +10.70% |
| Bloom Energy (BE) | +6.78% |
Moves are against Monday’s close, recorded at 8:00 a.m. Eastern Time on Tuesday.
In Simple Words
A stock-specific catalyst is a development that changes expectations for an individual company, such as higher guidance, a regulatory milestone or an upcoming earnings report. A proposed collaboration still needs to become a firm commitment, while an earnings announcement matters for both the completed quarter and management’s outlook.
Backblaze: Higher guidance puts cloud-storage momentum in focus
Backblaze enters Tuesday after raising its annual revenue and adjusted profitability forecasts. Its latest update showed faster growth in B2 Cloud Storage, supported by broader customer demand and larger accounts.

The outlook makes this more than a reaction to one completed quarter. Management expects another sequential increase in revenue, while the gap between cloud-storage growth and the weaker computer-backup business remains important to the company’s changing sales mix.
| Measure | Figure |
|---|---|
| Full-year revenue guidance | $177.8–$178.2 million |
| Previous revenue guidance | $172–$174 million |
| Full-year adjusted EBITDA margin guidance | 30%–31% |
| B2 Cloud Storage revenue growth | 47% year-on-year |
The forecasts were raised in Monday’s after-hours announcement.
Harmonic: A stronger forecast extends the overnight catalyst
Harmonic raised its annual revenue outlook after quarterly sales exceeded the top of its guidance range. Operating profit also improved substantially from a year earlier.
The forward order position adds substance to the upgrade. Backlog and deferred revenue increased sharply, giving investors another measure of demand alongside the completed quarter’s sales.

| Measure | Figure |
|---|---|
| Full-year revenue guidance | $545–$555 million |
| Quarterly revenue | $148.8 million |
| Revenue growth | 64% year-on-year |
| Backlog and deferred revenue | $534 million |
Backlog and deferred revenue were up 58% from a year earlier.
Aehr Test Systems: A raised outlook rests on stronger orders
Aehr Test Systems lifted its annual revenue outlook to the top of its previous range following record quarterly sales. Bookings exceeded revenue, supporting management’s assessment of expanding customer production requirements.
That relationship between orders and shipments is the key detail. The company’s effective backlog includes orders received after quarter-end, providing a more recent view of demand than the quarterly revenue figure alone.
| Measure | Figure |
|---|---|
| Fiscal-year revenue outlook | $150 million |
| Previous outlook | $130–$150 million |
| Quarterly bookings | $46.7 million |
| Effective backlog on November 1 | $109.3 million |
Management expects annual non-GAAP net income of at least 20% of revenue.

Lattice Semiconductor: The next-quarter forecast carries the story forward
Lattice Semiconductor reported record quarterly revenue and forecast another strong year-on-year increase in the following quarter. Compute and communications demand supported growth in its programmable-chip business.
Management also expects faster growth in industrial and embedded applications. That broadens the operating story beyond data centres, although the forward growth figures remain company expectations.
| Measure | Figure |
|---|---|
| Quarterly revenue | $291 million |
| Quarterly revenue growth | Approximately 118% year-on-year |
| Expected fourth-quarter revenue growth | Approximately 130% year-on-year |
| Expected industrial and embedded growth | Approximately 70% year-on-year |
The fourth-quarter growth rates are forecasts announced Monday evening.
Bloom Energy: California collaboration opens a development opportunity
Bloom Energy is in focus after California Resources announced a collaboration to evaluate fuel-cell power generation paired with carbon capture and permanent storage. The proposed developments would serve grid demand or customers directly at their sites.

The potential scale is substantial, but the agreement is preliminary. Definitive contracts, investment decisions and regulatory approvals are required before the contemplated projects can proceed.
| Measure | Figure |
|---|---|
| Target generation capacity | At least 1 gigawatt |
| Potential annual carbon capture and storage | Up to 3 million metric tons |
| Proposed location | Central and Northern California |
| Agreement status | Non-binding memorandum of understanding |
The capacity represents a development target, rather than a completed equipment order.
Compass Pathways: A near-term filing brings the regulatory timetable closer
Compass Pathways said Tuesday that the final submission of its application for COMP360 is nearing completion. The investigational treatment targets treatment-resistant depression, with a rolling review already underway.
The immediate catalyst is completing that submission. Management is also preparing for a potential commercial launch, but the timing remains dependent on FDA approval.

| Measure | Figure |
|---|---|
| Planned final application submission | Within two weeks |
| Expected launch window | First half of 2027, subject to approval |
| Quarter-end cash and equivalents | $444 million |
| Expected funding runway | Into 2028 |
The application timetable does not constitute approval to market the treatment.
Pfizer: Higher annual guidance shifts attention to the product mix
Pfizer raised its annual revenue and adjusted earnings forecasts on Tuesday. Growth outside its COVID products helped offset weakness in that part of the portfolio.
The guidance increase gives the session a fresh forward catalyst. The important operating question is how consistently the newer portfolio and cost improvements can support earnings as the sales mix changes.
| Measure | Figure |
|---|---|
| Annual revenue guidance | $62–$64 billion |
| Previous revenue guidance | $60.5–$62.5 billion |
| Annual adjusted diluted EPS guidance | $2.95–$3.05 |
| Previous adjusted EPS guidance | $2.80–$3.00 |
The updated earnings outlook includes the impact of an acquired research and development charge.

AMD: Tonight’s report provides the next company-specific test
AMD is scheduled to release its fiscal third-quarter results after Tuesday’s close. Management’s discussion will provide a fresh assessment of a business spanning cloud and AI infrastructure, personal computers, gaming and embedded computing.
The report creates a direct opportunity to assess demand, profitability and the outlook across those markets. The distinction between current shipments and expectations for subsequent quarters will matter to the interpretation of management’s comments.
| Measure | Figure |
|---|---|
| Reporting period | Fiscal third quarter of 2026 |
| Results release | After Tuesday’s close |
| Conference call | 5:00 p.m. Eastern Time |
These are confirmed announcement timings, rather than reported quarterly results.
Arista Networks: After-hours update puts networking demand in view
Arista Networks reports after Tuesday’s close, bringing its networking business back under scrutiny. Its products serve AI, data-centre, campus and routing environments.

|---|---|
| Quarter ended | September 30, 2026 |

Booking Holdings: Travel earnings arrive at the closing bell
Booking Holdings plans to publish its quarterly results around Tuesday’s market close. Its collection of travel platforms gives the announcement a different operating focus from the technology reports due the same evening.
The release and management discussion will provide an updated view of the company’s financial performance and travel business. The forward commentary will help place the completed quarter in context.
